Background: Experimental data indicate that low-flow reperfusion following prolonged cardiocirculatory arrest may aggravate early cerebral microcirculatory reperfusion disorders. We investigated the influence of cerebral reperfusion flow change to the ischemic histopathologic damage of brain tissue after incomplete forebrain ischemia in rats. Materials and method: Anesthetized Sprague-Dawley rats were undergone ligation of both internal carotid artery by microvascular clamp for 10 minutes. After release of the clamp, reperfusion was started with several different flow levels (0, 10, 20, 30, 50, and 100%) of internal carotid artery comparing to pre-clamping phase using flowmeter. After 15minutes of reperfusion, rat brains were prepared by perfusion-fixation with 3% formaldehyde. Under light microscopic examination of Hematoxylin-Eosin stained tissue slide, histopathologic damage was examined at cortex, putamen, and hippocampus regions. Categorical hisotopathologic damage scores were derived in each regions by manual counts of ischemic neurons. Result: The histopathologic damage scores were 0, 10.2±0.5, 7.6±1.5, 5.9±1.4, 5.0±2.8, 3.5±0.7, and 1.0±0.0 in control, 0, 10,20, 30, 50, and 100% reperfusion groups, respectively(p<0.05). Conclusion: Our results showed significant increment of brain histopathologic damage scores along with decreasing amount of cerebral reperfusion flow after incomplete forebrain ischemia. We believe restoration of reperfusion flow to pre-ischemic level would be a critical component in attenuation of brain ischemic damage.

송욱 시에 나타난 자연과 생명

정효구(Hyo-goo, Jeong) 어문연구학회 2010 어문연구 Vol.63 No.-

This paper is written under the premises that Song Wuk’s four collections of poetry emlxxiy the idea of 'principle of Tao' and ‘body of Tao.’ and that their metonymy. wruch include nature. body. life and universe, are regarded as the focal point of comprehending and solving problems. Song Wuk is a poet who approached the process of writing as a highly intellectual attitude. However. it was trus attitude that made rum realize the limitations of the intellect. especially that of the Western culture. He then discovered that beyond the realm of intellect exist the fundmental principle that governs the world, which exists in the vital forms of life. nature, body and universe. Based on such discovery. his poems carry certain significance in the rustory of Korean poetry. First. far from merely being one of many contemporary poets, Song Wuk is one of those who follow the tradition of Korean poet such as Han Yong-Un. Sea Jeong- Ju, Jo Ji-Hun. Kim Gwan-Sik. whose works are based on the Asian idea of Tao. Second, the idea of Tao that he portrays in rus works sucessfully integrates the worlds of Taoism, Buddhsism and Yin and Yang. and focuses on the world of Taoism, nature rather than that of artificiality. This is the point where the idea of Tao embodied in his works diverts from that of Congucianism and Wang Yangming. Third Song Wuk's exploration of the nature, body, uniiverse, and life based on the idea of Tao coincides with the extensive discussions about our body and ecology that has taken place in Korea since 1990s. His poems are in effect their precedents that pioneered the movement. By uncovering such characteristics of Song Wuk's poetry, this paper will contribute to expanding the understanding of his works, which has mostly been confined to acknowledging his use of intellectual satires, ironies and experimental Ianguages. Furthermore, by acknowledging such nature of Song Wuk's poems, we can comprehend the complexity of his poems, and appreciate and assess them with a better structural understanding.

Necrotizing fasciitis is defined as infectious disease showing extensive necrosis of the superficial fascia with widespread involvement of the surrounding tissues and concurrent systemic toxicity. It is found commonly in the extremities, the trunk and the perineum, but shows extremely rare occurrence in the well vascularized area such as head and neck area. Occurred in the head and neck area, it is called "cervicofacial necrotizing fasciitis" (CFNF). It is a fatal disease which carries a mortality rate up to 60%. Early diagnosis, aggressive surgical debridement of necrotic tissues and massive antibiotics therapy are essential for achieving a favorable outcome. We present a case of cervicofacial necrotizing fasciitis in 35-year-old male patient with literature review.

교사의 다문화 역량의 강화 방안 연구 : 미술 교과를 중심으로

김정효 한국문화교육학회 2011 문화예술교육연구 Vol.6 No.1

국제화·세계화의 추세와 함께, 한국 사회는 유학생, 국제결혼, 외국인 근로자 등 국내 거주하는 외국인이민자의 수가 증가와 함께 다문화 사회로 급변하고 있다. 이러한 한국 사회의 인구 구성의 변화는 학교에서 다양한 문화적·민족적 배경을 가진 학생들의 수가 증가하고 있음을 의미한다. 소수의 다문화 배경의 학생들과 다수의 한국 학생들이 세계에 능동적으로 대처하고 자아실현을 할 수 있는 사회의 구성원으로 성장하도록 하기 위해서, 모든 학생들이 문화적으로 민감하게 반응하고 대처할 수 있는 능력을 육성하는 교육이 요구된다. 다문화 시대에 학생들과의 상호작용으로 교육을 실천하는 교사들의 문화적 역량이 학생들의 학교에서의 성공적인 학습경험을 이끌어 내는 데에 가장 결정적인 요인으로 작용한다. 본고에서는 다문화 시대에 요구되는 교사의 문화적 역량에 대하여 미술 교과를 중심으로 살펴보았다. 교사의 다문화 역량의 개념을 여러 학자들이 제시한 문화적 역량의 특성들을 통하여 살펴보았다. 다음으로, 미술 교육을 통해서 육성될 수 있는 다문화 역량과 미술 교육에서 요구되는 교사의 다문화 역량을 논의하였다. 마지막으로 교사의 다문화 역량 강화를 목적으로 한 외국의 교사 교육 프로그램과 현장 교사들의 다문화 역량 증진의 예를 제시하고, 교사의 다문화 역량 증진을 위한 시사점을 논의하였다. Along with the globalization of the world, Korean society has become multi- cultural in terms of the continuous increase in number of international students, international marriages, and foreign workers. The radical change of population of Korean society signifies the increase in number of the students with multi-cultural, ethnic background in schools. Education is needed for both a minority of students with multi-cultural backgrounds and a majority of Korean students, which helps promote the capability of the students to culturally respond to the world, and all of the students to reach self-realization in the future. It is culturally responsive competence of teachers that is the critical factor in leading to student' successful learning experience in schools. This study focuses on exploring cultural competence of teachers required to raise students cultural competence and responsiveness through visual arts. First, the concepts of cultural competence of teachers are investigated by centering on what scholars have studied. Next, the cultural competence of students fostered through visual arts and one of teachers necessary for teaching visual arts are discussed. Last, the examples of teacher preparation programs that are set up for nurturing teachers' cultural competence at universities and a community of practice of elementary art teachers are introduced as an exmplar to show how art teachers, cultural competence can be developed through participating in a learning community. And the indications for developing Korean teacher preparation programs are discussed.

In the elderly population, there is a strong relationship between cognition and the level of physical activity. The purpose of this study was to evaluate cognitive function and activity level of daily living and to investigate correlation between Mini-Mental State Examination(MMSE), and Functional Independent Measure(FIM) in elderly with Alzheimer's dementia. Of the 15 subjects enrolled in this study, sixties and seventies were each 26.7%, and eighties was 46.7%. MMSE mean scores was 15.40±4.69, and FIM mean scores was 87.53±7.79. The scores of 'registration memory' item of MMSE was highest level(100%) but, the scores of 'recall' item was lowest level(11.11%). In MMSE and FIM, there were no significant difference by age (P=0.185, P=0.329). MMSE-FIM scores was significantly correlated (r=o.856).

포토캐소드를 이용한 발광소자 제작에 관한 연구

정효수 水原大學校 2014 論文集 Vol.28 No.-

상압에서 제조된 포토캐소드(photocathode)를 이용하여 진공소자를 제작하였다. 발광을 위하여 양극기판에 R, G, B 형광체를 도포하였다. 제작된 진공 발광소자에 전압을 인가하여 밝기, 소모전력, 효율 등 발광특성 및 성능을 평가하였다. 전압인가 방식으로는 전류제한이 없는 high power mode와 전류를 제한하는 low power mode를 적용하였다. 전자방출을 유발하는 광원으로는 가시광 영역인 450 nm의 청색 LED 면광원을 사용하였다. 상압에서 제작된 포토캐소드는 전자방출 특성에서 높은 전류밀도와 장기적인 안전성을 나타내었다. 일반적인 포토캐소드 제조와 비교할 때 제작공정이 단순하여 저렴하게 제작할 수 있고, 선택적인 가시광영역의 광원에 감지도가 좋은 특성을 그대로 나타내었다. 제작된 면발광소자는 전압인가 방식에 따라 밝기, 전력소모, 효율 등에서 분명한 차이를 나타내었다. 이것은 응용분야에 적합한 밝기와 전력소모, 효율 등을 선택할 수 있다는 것을 의미한다. 측정된 값은 광원으로 사용하기에 충분한 평가지표를 나타내었다. 따라서 포토캐소드 면발광소자는 일반광원뿐만 아니라 UV 면광원과 같은 첨단 광원개발에 응용될 수 있을 것으로 보인다. 또한, 포토캐소드의 상압 공정기술은 전자원 뿐만 아니라 일반적인 전자소자에도 응용할 수 있을 것으로 보인다.

가토에서 경정맥 이식을 이용한 요도결손 재건술

There are several methods for the reconstruction of partial urethral defect, including split-thickness skin graft, full-thickness skin graft, and preputial flap and free flap. Despite partial success using these methods, most results are unsatisfactory due to frequent complications such as postoperative infection, fistula formation, hair growth and stricture. There have been several pioneering experiments in this field using autogenous vein graft and the results have been controversial. However, the fact that the endothelial lining is replaced by natural urethral epithlium is generally accepted as a positive effect of this method. This experiment was designed to identify the possibility of using vein graft for the reconstruction of partial urethral defect. Two different types of vein graft method were performed in a total of 20 New Zealand White rabbits with partial urethral defect. Firth, for the patch-graft group, a 1×1 cm rectangular vein graft was sutured at a defective area of the same size. Second, for the tubed-graft group, a vein graft segment 1 cm long was replaced at a segmental urethral defect of the same length. Histologic study was performed at three and eight weeks postoperatively in each group. The process of transitional ell epithelial replacement within the grafted vein was uniformly observed in both experimental groups at three weeks postoperatively. At eight weeks postoperatively, the epithelial replacement was almost complete and histologically undistinguishable. In the retrograde urethrogram performed after 8 weeks, the urinary flow in the patch-graft group was normal and showed no stricture, and two of five rabbits in the tubed-graft group showed partial stricture at the graft site. In conclusion, natural urethral epithelium was restored in grafted venous segments irrespective of the type of graft. Partial stricture was observed in 40% of the tubed-graft group while complete reconstruction was possible in the patch-graft group.
